Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Inspection Across San Mateo
A chimney inspection in San Mateo typically runs $149 – $289 for a standard Level 1 check, and most inspections we book here are completed within a few days. For Baywood, Aragon, Shoreview, or the Marina area, our crew comes prepared for older tile liners, marine-layer moisture, and the kind of crown wear San Mateo’s damp winters create. If you need a straight answer about whether your fireplace is safe to burn, call us at (830) 251-4560. Hank Delano runs every inspection job through the same discipline: written price before work starts, camera evidence when it matters, and no recommendation without a photo you can see with your own eyes.
Why Flint Chimney Sweep Is San Mateo’s Preferred Chimney Inspection Company
San Mateo homeowners tend to know their houses. A lot of the homes we inspect here were built between the 1920s and 1960s, and the original clay tile liners in those chimneys are often undersized or offset in ways a quick visual check misses. That’s why we put a camera up the flue on nearly every inspection we do in San Mateo. You get the report. You see what we see.
Flint Chimney Sweep has been operating since 2002 as part of the Garrison Partners family of chimney service companies. Every technician who shows up at a San Mateo address is background-checked and uniformed. You know who’s walking through the door because you approved the appointment with a live person on the phone. No voicemail trees, no callback forms.
We follow the same Garrison Standard as every other Garrison Partners location. That means a written price before any work begins, a 365-Day Done Right Promise on repairs, and a free return visit if a covered repair fails within the one-year guarantee period. Those are written terms, not verbal assurances.
Response time to San Mateo neighborhoods like Baywood Knolls, San Mateo Park, and Hillsdale is typically 2 – 4 business days for inspections. We schedule around the marine layer when we can: roof work in damp conditions is slower and less safe for footing, so we plan accordingly.
Fireplace Inspection in San Mateo
Fireplace Inspection in San Mateo means checking what’s visible and what isn’t: the firebox, damper, smoke chamber, flue liner, crown, cap, and flashing. A lot of companies do the first four and stop at the roofline. We don’t. San Mateo’s winter rain and morning fog keep chimney exteriors damp for days at a time, and that moisture is what causes mortar joints to spall and crowns to crack. So when we inspect a fireplace in San Mateo, we spend as much time on the roof as we do inside the firebox.
The inspection itself runs $149 – $289 for a standard visual and camera check. If you’re buying or selling a home in San Mateo, a Chimney Inspection with photo documentation is usually required by the listing agent or lender before closing. We write those reports so they hold up in escrow.
When San Mateo Homeowners Call Us
Most calls come in October and November, right before burning season. The second biggest spike is April, after a winter of rain exposed a leak around the flashing. Then there are the real estate transactions year-round: houses in San Mateo Village, North Central, and the 19th Avenue corridor change hands constantly, and every one of those deals needs a documented inspection.
What the Camera Catches
The camera run is the difference between guessing and knowing. A Level 1 inspection looks for creosote buildup, blockages, and obvious damage. A Level 2 adds the video scan of the flue interior. In San Mateo houses built in the 1940s and 1950s, we regularly find hairline cracks in the original clay tiles that a mirror-and-flashlight check would never reveal. We show you the footage. You decide with the evidence in front of you.
Chimney Inspection Services in San Mateo
Chimney Inspection Services in San Mateo cover three levels of depth, and we’ll tell you plainly which one your chimney actually needs. A Level 1 runs $149 – $289. A Level 2, which adds the full camera scan and is required for any real estate transaction or after a chimney fire, runs $289 – $449. A Level 3 is a more invasive inspection, typically only called for after a suspected fire event or significant structural concern, and we quote that after we’ve seen the Level 2 results.
Every inspection ends the same way: with a written report and photo documentation of anything that needs attention. In San Mateo, where we work on San Mateo homes from Hillsborough border to Foster City line, that paper trail matters. It’s the reason real estate agents and escrow officers in this city keep our number on file.
Flue and Camera Work
The flue is where most chimney problems live, and San Mateo’s damp air makes things worse. Cold liners condense smoke more readily, which leads to faster creosote adhesion. A camera inspection shows us the exact location and severity of any deposit. For eucalyptus burners, that’s usually a light, fluffy first-degree creosote that brushes off. For homes burning unseasoned wood or running a lazy draft, it can be a hard, tar-like second-degree coating.
Real Estate Inspections
We do a high volume of real estate inspections in San Mateo because the city has one of the highest turnover rates on the Peninsula. These are Level 2 inspections almost always, because the contract requires a documented flue condition. We deliver within 48 hours of the inspection, formatted for the escrow timeline.

Trusted Brands We Service in San Mateo

We bring what the specific chimney requires and put the brand name on your written estimate before any work starts.
Common Chimney Inspection Problems We See in San Mateo Homes
- Marine-layer crown spalling: San Mateo’s fog drip and winter rain keep chimney crowns wet for extended stretches. Combined with occasional freeze-thaw cycles in higher elevations like the Sugarloaf area, this accelerates the pitting and cracking of the concrete crown. We check the crown every inspection and document every crack with a photo.
- Undersized or offset clay tile liners in 1940s construction: A 1940s San Mateo bungalow on a street like Alameda de las Pulgas often has an original clay liner sized for a much smaller box. We see offset tile installations that create ledges where creosote accumulates. The camera catches these because a visual sweep cannot.
- Damp air and first-degree creosote buildup: San Mateo’s coastal air means chimneys stay cool on the exterior, which encourages creosote condensation on the flue walls. Homes that burn eucalyptus or unseasoned wood are especially prone. The good news: first-degree creosote brushes off easily. The bad news: ignoring it leads to second-degree buildup, which does not.
- Missing or damaged chimney caps and spark arrestors: The wind coming off the Bay and through the San Mateo Gap can carry embers, and it also drives rain directly into uncapped flues. We regularly find rusted-out steel caps on homes in the Shoreview and Marina Lagoon areas. A broken cap is a cheap fix and a recurring inspection finding.

FAQs About Chimney Inspection in San Mateo
Every year if you burn regularly, and immediately if you’ve had a chimney fire, noticed a change in draft, or bought a house with an unknown chimney history. The National Fire Protection Association standard is annual inspection, and we follow that. For occasional burners in San Mateo who only light a fire on rainy weekends, an inspection every two years is defensible, but the first one should include a camera scan so you have a documented baseline. Call (830) 251-4560 and we’ll book it.
Yes. Third-degree creosote looks like shiny, tar-like glaze stuck to the flue walls, and it is the dangerous kind because it burns hot and is nearly impossible to remove with a brush. We can identify it during a camera inspection before any sweeping takes place. If we find it, we’ll tell you straight: this is a repair situation, not a sweep situation. In San Mateo homes burning unseasoned wood, this is the failure we watch for. You’ll see the footage yourself before you approve anything.
Yes, and it matters. A 1940s San Mateo bungalow on a street like Baywood Avenue was typically built with a clay tile flue liner sized to the era’s smaller fireboxes and often installed with offsets or joints that modern builders wouldn’t accept. We assume nothing about liner size or condition on older homes. The camera run is not optional for these. We also check for the original damper’s condition: many 1940s dampers are rusted or partially seized, and that changes draft behavior. Call (830) 251-4560 for a quote.
Every inspection covers the firebox, damper, smoke chamber, flue liner, chimney cap, crown, flashing, and the roof seal. We look at creosote levels, blockages, cracking, water intrusion, and clearances. In San Mateo, the exterior components get extra attention because of the marine layer’s effect on mortar and concrete. You’ll receive a written report with photos for anything we flag. That’s the whole point: you don’t have to take our word on a repair recommendation.
Yes, and it is one of the cheapest insurance policies on the house. San Mateo’s winter rains and fog drive moisture directly into open flues, and that water accelerates liner cracking, damper rust, and smoke chamber spalling. A proper cap with a spark arrestor also keeps embers from landing on the roof, which matters in a city as dense as San Mateo. If yours is missing or rusted out, we’ll include the replacement in your written estimate before any work starts.
